It's about as sharp as you will make a steel knife without taking a strop to it. That is it slices paper like all the demos you see on youtube, it won't shave the hair off the back of your arm, but, it will slice through 8mm poly double braid without any fuss at all. (Which is more important than shaving your arm bald!)
It clicks closed, so it won't pop open accidentally. And it locks open.
It feels light, but not in any way flimsy. It takes a little practice to pop it open without your thumb getting too close to the blade, it sort of pops, and your thumb can slip of the stud. The blade is only an inch wide, if the back of the blade was a bit wider, there'd be more room for the thumb stud.
On the whole a very nice toy. I can't help thinking my modified Myrchin will still be my go too knife on the boat, 'cause I know it's bullet proof. But I suspect that this one will have it's place too. I just want to see how resilient it is.
But on the whole nice toy.
